Du Guesclin, Bertrand, constable of France, born in Côtes du Nord; one of the most illustrious of French war-captains, and distinguished as one or the chief instruments in expelling the English from Normandy, Guienne, and Poitou; was taken prisoner at the battle of Auray in 1364, but ransomed for 100,000 francs, and again by the Black Prince, but soon liberated; he was esteemed for his valour by foe and friend alike, and he was buried at St. Denis in the tomb of the kings of France (1314‒1380).
